Answer:
The answer is the mutations within the genetic code.
Step-by-step explanation:
Natural selection is one of the basic mechanisms of evolution by which species adapt to their environment in order to increase their chance of survival and reproduction. In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. But, the sources of this genotype variations are not changes in the environment, nor response to the stress, but the mutations in the genome of the organism. If a mutation is not lethal, it could remain in the population, increasing the variation is some traits.
Hope this helps !!!!!!!!!!!!!!!!!
For this case we have the following rule of three:
12 ----> 100%
8 ------> x
Clearing x we have:
x = (8/12) * (100)
x = 66.66666667% (percentage of correct answers)
For 20 baskets we have:
20 -----> 66.66666667%
x -------> 100%
Clearing x we have:
x = (100 / 66.66666667) * (20)
x = 30 attempts
Answer:
To make 20 canatas, 30 attempts must be made.
In the region 0-2, the first derivative has a zero at x=1, and the second derivative (slope of the first derivative line) is positive. This means f(x) will have a minimum at x=1.
Likewise, in the region 4-6, the second derivative is negative and the first derivative is zero at x=5, indicating a maximum there.
These observations narrow the selection to choices A or C. The derivative curve is continuous at x=2 and x=4, so there will not be any discontinuities in f(x)--eliminating selection C.
The best choice is
A.
Answer:
Lim (f(9+h)-f(9))/h as h->0 = 2916
Step-by-step explanation:
f(x)=x⁴
f'(x)
= Lim (f(9+h)-f(9))/h as h->0
= 4x³
At x = 9, f'(x) = f'(9) = 4*9³ =4*729 = 2916
Answer:
60
Step-by-step explanation:
Simplify the following:
4×9^2/27×5
9^2/27×5 = (9^2×5)/27:
4×(9^2×5)/27
4×(9^2×5)/27 = (9^2×5×4)/27:
(9^2×5×4)/27
9^2 = 81:
(81×5×4)/27
81/27 = (27×3)/27 = 3:
3×5×4
3×5 = 15:
15×4
15×4 = 60:
Answer: 60
